Super Mario Maker doesnt't finish loading extra data

This all happens just after you open the game.
The game stays waiting forever for extra data to be created or loaded.
First time, it says that extra data is being created, and actually, the files are created into “sdmc\Nintendo 3DS\00000000000000000000000000000000\00000000000000000000000000000000\extdata\00000000\00001A04\user”. But it just doesn’t continue. I waited almost for 1 hour and nothing. I closed the game and launched it again. This time it says “Loading extra data”, the same, waited about half hour and nothing.
However, it’s not hung. There is a dove picking some seeds unfailingly.

that is a known issue, thanks for reporting it

Copy the files “course0” to “course220” to another folder. Then delete the files on “sdmc\Nintendo 3DS\00000000000000000000000000000000\00000000000000000000000000000000\extdata\00000000\00001A04\user”. After that, the bird would finsh eating. Then return the copied files. That’s what I did. Citra Build: Canary 1215 (Even though they’ll replace the files with new ones, you still have to return the copied ones for the custom courses’ data)

After putting course0 and course220, it froze again, are they needed?

Put them back at the title screen. Also, I meant course0 - course 220, but you actually don’t need to copy them all. Instead, count the number of courses you’ve created on Coursebot, and copy course 0 to course(number of courses in coursebot -1). The reason why you’ll do this is for the sake of your course data, beacuse for some reason, Citra won’t load the extra courses. I think problem was fixed after updating to the latest version.
